摘 要: | 采用经颅超声多普勒(TCD),对38例癫痫病患者发作间期的脑动脉平均血流速度(Vm)进行了观察。结果38例中6例正常,4例Vm增快,3例Vm减慢,22例表现为双侧血流速度不对称(BAV),3例BAV并Vm增快或减慢,脑动脉Vm异常发生率为84.21%(32/38)。说明癫痫发作间期脑动脉血流速度可有一定程度的异常改变,其异常改变的主要形式为BAV。

Changes of Blood Flow Velocity in Basal Cerebral Arteries in Patients with Epilepsy during Interictal Period |

Abstract: | Changes of blood flow velocity of basal cerebral arteries were studid in 38 epileptic patients during interictal period by using transcranial Doppler ultrasound(TCD).The mean velocity(Vm)was normal in 6 patients,increased in 4 patients,decreased in 3 patients,bilateral asymmetrical Vm(BAV)was found in 22 patients,and BAV with Vm increasing or decreasing existed in 3 patients.The abnormal of Vm was 84 21%(32/38).Results indicated that some disorders of blood flow velocity in basal cerebral arteries might occur in epilepsy patients during interictal period,and the major abnormal type of velocity is BAV. |
